Federal Railroad Administration

rosaP Repository & Open Science Access Portal

The Federal Railroad Administration (FRA) promotes safe and environmentally sound rail transportation. The FRA conducts research and development tests to evaluate projects in support of its safety mission and to enhance the railroad system as a national transportation resource. Public education campaigns on highway-rail grade crossing safety and the danger of trespassing on rail property are also administered by FRA.

    Slot welding is a new method that can be used to repair defects that may be present in the head of the rail. In this method, instead of using a plug rail as is done in all other defect removal techniques, the defect is removed from the railhead via machining a perpendicular slot containing the defect. The slot is then heated to a specified temperat ...
